Broadcast 255.255.255.255 across vlans
-
I have a device that I'm using that does its discovery by doing a udp broadcast on 255.255.255.255 on port 9999.
That device is on a vlan with a subnet of 192.168.20.0/24 The server that I want to respond is on a different vlan with a subnet of 192.168.1.0/24. I've been trying to get IGMP proxy to forward the broadcast to the server's vlan but I can't seem to see message leave the vlan at all.
My current IGMP Proxy config looks like
My firewall rules look like this but I can't get the traffic to show at all
Any ideas on what I'm doing wrong or if this is possible?

Routers don't pass broadcasts.

@jknott is it not possible for a pfsense plugin to listen for the broadcast and then rebroadcast it to another vlan?

This will probably do it: https://forum.netgate.com/topic/155698/how-can-i-get-this-udp-relay-package-for-casting-across-vlans
Or you could try PIMD bur the UDP broadcast relay is more likely IMO. Requires some work to setup though as it's not a pfSense package.Steve
